Automotive engineering: “Adhesion from the plasma nozzle”

Only a vision just 25 years ago, plasma from the nozzle now sets the standards for the pretreatment of material surfaces prior to bonding in virtually every sector of industry all around the world. Automotive engineering in particular has benefited from the atmospheric pressure plasma process first integrated into series production in the mid-90s. ADHESION Adhesives & Sealants (4[12]/2018) reports.

Plasma-SealTight®: No chance for corrosion

The migration of moisture in combination with oxygen at the interface of an injection molded plastic-to-metal joint can lead to corrosion and premature adhesive failure of the hybrid component. The innovative Plasma-SealTight® technology aims to combat this issue in the long term. DICHTUNGSTECHNIK JAHRBUCH 2019 (THE YEARBOOK OF SEALING AND GASKET TECHNOLOGIES 2019) describes the process in detail and reports on the outstanding test results.

180 degree turn in the pretreatment process

In search of an environmentally friendly method for optimizing the adhesion of their aluminum housings, lighting manufacturer Waldmann struck lucky when they found Plasmatreat. Instead of solvent-based cleaners and primers, the company now uses Openair-Plasma® to achieve a tight seal and stable adhesive bond for their surface-mounted LED machine lights. The specialist journal WOMAG (10/2018) reports.

Dispensing with chemicals: Environmentally friendly pretreatment of plastics in the automotive industry

For non-polar plastics, surface activation is essential to ensure the reliable, long-time stable adhesion of adhesive bonds and coatings. The development of Openair-Plasma® technology 20 years ago created a solution which the automotive industry had long been seeking: an alternative to wet-chemical pretreatment processes for material surfaces. WERKSTOFFE (9/2018) reports.

It's all about surface energy

The reason why adhesive or paint does not readily adhere to clean plastic surfaces is generally because the surface energy is too low. A pretreatment with plasma can quickly remedy this problem. The annual magazine KUNSTSTOFF + VERARBEITUNG 2018 reports how Openair-Plasma® satisfies the automotive industry's strict technical and quality requirements.

Using atmospheric pressure plasma

Through the development of plasma nozzles in 1995, Plasmatreat established an atmospheric pressure plasma technology in manufacturing technology which can be integrated into continuous, fully automated production processes. The WOTECH Special "Basiswissen Prozesskette Oberflächentechnik 2018" (Fundamentals of Surface Technology 2018) describes the process and outlines today's use and future application possibilities.

Chrome-free protection – Plasmatreat in the aluminum industry

There are alternatives to environmentally harmful, energy-intensive pretreatment processes in the aluminum processing industry. The use of atmospheric pressure plasma is a particularly energy-saving option. In a special edition, leading German trade journal for the aluminum industry ALUMINIUM-PRAXIS (6/2018) reports on the benefits and applications of Plasmatreat technologies.

What solutions does your company offer to new trends in adhesive bonding technology and where do the challenges lie? How do you ensure knowledge transfer to users and what role do services play in your projects? The specialist journal DICHT! (No. 2(6)/2018) asked selective companies to respond to these questions.
